GRAIN-DOOR.

SPECIFICATION forming part of Letters Patent N0. 778,946, dated January3, 1905.

Application filed June 10, 1904. Serial No. 211,946.

To aZZ whom it may concern:

Be it known that we, ULYSSES M. BOGARD and ALBERT L. MAPLE, citizens ofthe United States, residing at Glasford, in the county of Peoria andState of Illinois, have invented certain new and useful Improvements inGrain- Doors; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention has reference to doors for grain-cars, and relatesparticularly to the supporting and fastening devices therefor.

The invention has for its object a car-door which is made in twosections for the purpose of increasing the length of the door as the caris filled with grain and the same have a telescopic relation withswingably-supported hangers for raising said doors out of position.

The invention consists, further, in the support for a car-door whichcomprises a rod journaledin suitable bearings attached to the body. ofthe car, which is provided with depending integral rod portions whichhave a telescopic relation with tubular members attached to the face ofthe grain-door, of a pair of coil-springs wound around thefirst-mentioned rod, one end of said spring fixed in the woodwork of thecar, and the opposite end bearing against the outer face of thedepending rods for the purpose of assisting in raising the car-door andto also prevent lateral displacement of the depending hangers, also thethe grain-door during any sudden jar or motion of the car. Y

The invention consists of certain other details of construction to bemore specifically set out in the specification and illustrated in theaccompanying drawings, in which Figure 1 is an inside elevation of acar-door and the mechanism for supporting and raising such door. Fig. 2is a vertical section taken on the line a a of Fig. 1. Fig. 3 isasectional detail to show the door as it appears when raised and lockedin position against the roof of the car. Fig. 4 is a detail in frontelevation,showing the manner of locking the graindoor to the body of thecar.

Like numerals of reference indicate corresponding parts throughout thefigures.

1 denotes the body of the car, only a portion of its flooring, the sidesills for the door,

and a longitudinal sill of its roof being shown, and is deemedsufiicient to illustrate the application of our invention thereto. Thedooropening of the car is indicated as 2 and the main section of thegrain-door as 3, which is of a suitable height and is of sufficientwidth to extend across the door-opening 2 and have a bearing against theinner face of the posts or sills forming the side framework of saidopening. When the door 3 is in the position shown in Figs. 1 and 2, wehave provided for rigidly fixing or locking the same in such a position.This we accomplish through the pivoted latch 4:, which has a short stud5, adapted to engage and be forced into an opening in the side sills orposts of the door-opening. Thus to remove the door 3 either by raisingor swinging the same it will first be necessary to swing the latch 4 andrelease the stud 5, when the door may be moved to some other desirableposition.

6 denotes a longitudinally-carried rod adapted to lie parallel with andadjacent to one of the longitudinal beams forming the roof of the car,and said rod is journaled in the boxing 7, suitably attached to saidbeam, and 8 indicates a pair of depending rods which are integral withthe rod 6, and the body of said rods have a telescopic relation withtubes 9,attached to the front face of the door 3, said rods when thedoor is in its lowermost position extending into the tubes 9 to give thesame a bearing or a purchase to adapt the raising of the door in themanner to be described.

10 denotes a second section of the door 3, and is hung upon the rods 8by means of the angular plates 11, which are attached to the body of thesection 10 and are provided with an elongated slot, (not shown,) throughwhich the rods 8 pass. In the position shown in Fig. 1 the sections ofthe door are in their lowermost position and of a convenient height forshoveling grain into the car. As the grain reaches the height of thedoor, as is now shown, the section 10 is elevated on the rods 8 untilits lower 13 denotes a pair of coil-springs of the proper tension, whichare carried on the rod 6, one end fixed to the body of the car, as at14, and their opposite ends dropped down and having angular extensions15 bearing or exerting pressure against the outer faces of the'extremeupper portions of the rods 8. These springs serve a double purpose:first, they assist the operator when swinging the door inwardly andupwardly out of position; secondly, the fixing of the springs in thebody of the car prevents any lateral movement of the rod 6 and also anydisplacement of the door by reason of any jar or movement of the car.

To raise the door out of position to permit of the removal or dischargeof the grain contained in the car, the door may be raised by inserting abar beneath the cleat 16, attached to the lower outer face of thesection of the door 3 when the operator may raise the door in a verticalline,permitting the tubes 9 of said door to telescope over the rods 8,and when the door reaches its extreme upper position the plates 11 willengage with a bowed portion 17 of the rods 8, andacatch 18, which has ahinged joint with the body of the door, is caused to engage with the rod6 and serves as a hanger for the forward end of the door when in suchraised position, (see Fig. 3,) and the lower or what may be termed therear end of the door when in such raised position may be held soelevated by some suitable catch, (not shown,) attached to the roof ofthe car.

We are aware that a grain-car door is not new and that to elevatesuch adoor on rods and to swing the same out of position is not new; but we donot know of a car-door which.

is made in two sections for the purposes herein, which have a telescopicrelation with hangers which are integral with a swingably-supported rod,nor are we aware of the use of coil-springs serving to assist inelevating the door and the further purpose of preventing lateraldisplacement, nor to the particular form of latch for locking the lowersection of the door when in its lowermost position.

It is obvious that the details ofconstruction may be modified andequivalents resorted to without affecting the principle and scope of theinvention.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent of the United States, is

1. In a device of the class described,the combination of a grain-doormade in two sections, a pivotally-mounted rod having integral dependingportions telescopically connected with the door, and coil-springs on thepivoted rod, adapted to prevent longitudinal movement of the rod in itssupporting-journals, substantially as specified.

. 2. In a device of the class described,the combination of a grain-doormade in two sections, a pivotally-mounted rod having integral dependingrods, tubes on the outer face of one section of the door with which thedepending rods have a telescopic relation, angular plates on the othersection by means of which said section is hung on the rods, andcoil-springs on the pivoted rod, with one end of the springs fast in asupport and the opposite end exerting pressure upon the depending rods,substantially as specified.

3. In a device of the class described,the combination of a grain-doormade in two sections, a rod, with integral depending portions, pivotallyconnected with the door-frame, springs to prevent longitudinal movementof the rod and assist in swinging the door to a horizontal position,tubes on the lower section of the grain-door with which the dependingrods have a telescopic relation, the upper section slidably arranged onthe depending rods by angle plates, said section adapted to drop downagainst the inner face of the lower section, levers with studs thereonengaging the framework of the door to lock said door in position,substantially as described.

4. In adevice of the class described,the combination of a grain-doormade in two sections, tubes on the lower section with which dependingrods on a pivoted rod have a telescopic connection, springs on saidpivoted rod to prevent longitudinal movement of said rod and assist inswinging the door to a horizontal position, angular plates witheye-holes engaging the depending rods, on the upper section, levers withstuds thereon on the lower section and hooks on the door-frame engagingthe upper section when raised to lock the grain-door in position, acleat on the lower section to aid in prying the door up, a hook to lockthe door in its telescoped condition to the pivoted rod and a suitablehook to lock the door in its telescoped condition in a horizontalposition to thel ceiling of the car, substantially as specifiec Intestimony whereof we affix our signatures in presence of two witnesses.
